Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

Specification of nano hydrophobic fumed silica sio2 treated fumed silicon dioxide HB-615 white carbon black powder factory

This HB-615 nano hydrophobic fumed silica powder is white carbon black. It is made using a special flame process. This creates very small particles. The particles have a high surface area. This powder is treated. The treatment uses silicone oil. This treatment makes the powder repel water. It becomes hydrophobic.

The powder particles are very small. They are in the nanometer range. This nano size gives it unique properties. The high surface area is important. It allows for strong interactions with other materials. The hydrophobic treatment is key. It prevents the powder from absorbing moisture. This keeps it free-flowing. It also helps it mix well into non-polar systems.

HB-615 powder improves performance in many products. It works well in silicone rubber. It makes the rubber stronger. The rubber also becomes easier to process. It is used in coatings and paints. Here it acts as a thickener. It prevents sagging. It improves the finish. The powder is good in adhesives and sealants. It controls viscosity. It prevents settling. It adds reinforcement.

This powder is useful in plastics. It increases strength. It improves scratch resistance. The hydrophobic nature is vital. It ensures good dispersion in oils and resins. It stops clumping caused by moisture. The powder is stable. It performs well in demanding conditions.

The factory makes HB-615 to strict standards. Quality control is constant. Every batch is tested. Tests check particle size. Tests check surface area. Tests confirm the hydrophobic level. The powder is pure. It has low impurity levels. This ensures reliable results. Customers get consistent performance. The powder is packed carefully. This protects it during shipping.

Applications of nano hydrophobic fumed silica sio2 treated fumed silicon dioxide HB-615 white carbon black powder factory

This nano hydrophobic fumed silica powder, HB-615, comes from our factory. It is very fine white powder. We treat fumed silicon dioxide specially. This treatment makes the powder strongly repel water. It hates water. This is its key feature.

HB-615 powder is super useful. It keeps things dry. It stops moisture damage. Manufacturers add it to many products. It improves performance significantly. Add it to coatings and paints. The coating then resists water very well. Rain slides right off. Dirt washes away easily. Surfaces stay cleaner longer. This is great for building exteriors and car finishes.

Plastics benefit too. Mix HB-615 into plastic compounds. It makes the plastic stronger. It makes the plastic harder. The plastic also becomes much more water-resistant. This prevents swelling or weakening. Electronics housings and outdoor gear need this protection. It extends product life.

Rubber formulations use HB-615. It reinforces rubber tires and seals. The rubber grips better. It wears down slower. Water cannot penetrate as easily. Seals stay tight. This prevents leaks in machinery and vehicles.

Adhesives and sealants get an upgrade. Adding HB-615 powder makes them stick reliably even in damp places. They cure properly with moisture present. They resist peeling off. Construction and repair jobs need this reliability. It prevents bond failure.

HB-615 works in cosmetics. It gives powders a smooth, dry feel. It helps control oil on skin. Makeup applies evenly. It lasts longer on the face. Personal care products feel lighter and less greasy.

Printing inks use it. The ink dries faster on paper. Smudging is reduced. Text and images stay sharp. Print quality improves noticeably. This matters for packaging and publications.

This white carbon black powder is a versatile additive. It solves moisture problems across many industries. Our factory ensures consistent quality HB-615 powder. It delivers reliable hydrophobic performance.

5 FAQs of nano hydrophobic fumed silica sio2 treated fumed silicon dioxide HB-615 white carbon black powder factory

Here are 5 common questions about our nano hydrophobic fumed silica (SiO₂), HB-615 white carbon black powder:

What exactly is HB-615 powder? It is very fine white powder. We make it from fumed silicon dioxide. Then we treat the surface. This treatment makes it repel water. We call this hydrophobic. The particles are extremely small, nano-sized.

Why make the silica hydrophobic? The hydrophobic treatment changes how the powder behaves. Untreated silica attracts water. Our HB-615 pushes water away. This stops clumping from moisture. It makes the powder flow much better. It also helps the powder mix evenly into other materials.

Where is HB-615 powder typically used? You find it in many industries. It thickens silicone sealants and coatings. It reinforces rubber products. It prevents caking in paints and plastics. It acts as a free-flow agent in powders. It is good for systems needing water resistance.

Is HB-615 powder safe to handle? Handle it like any fine powder. Avoid breathing the dust. Use normal ventilation or a mask. Wear gloves and eye protection. It is not classified as toxic. Always check the Safety Data Sheet for full details. Follow standard industrial safety practices.

How is HB-615 different from untreated fumed silica? The key difference is the surface. Untreated silica has hydroxyl groups. These attract water strongly. Our HB-615 has a special coating. This coating blocks the water attraction. The result is a dry, free-flowing powder. It performs better in non-polar systems.
